METHOD AND MIEANS FOR PUNGHING.

Application filed February 8, 1921.

To all whom if; may concern Be it known that I. LOUIS RosnN'rHAL, a citizen of the United States. residing at Philadelphia, in the county of Philadelphia,

Stateof Pennsylvania, have invented a new and useful Method and Means for Punching. of which the following is a specification.

This invention relates to punching. The

0 object is to provide improved method and means for punching one or more holes in a sheet or sheets. in exact relative position or positions with respect to each other or with respect to certain devices which have been printed or which are to be printed or otherwise marked upon the sheet.

The invention is especially applicable to the method and means for punching the necessary hole in the exact center of the label used upon phonograph records. This also means that the hole must be in exact register with the center of the printed matter upon the label; and. since the printed matter for a number of labels is printed upon a sheet of paper. before the labels are cut from the sheet. it follows that the centrally disposed holes for these labels must be not only inproperregister with respect to the printed matter of each label. but

they will also have a certain relationship with each other. so that if one of a group of holes be in proper register with respect to its label. the other holes will also be in proper register. each with its respective label.

The invention comprises a suitable comhination of punching instrumentalities associated and operated in definite relationship with the press which applies the printed matter to the sheets. The operation being such that the punching instrumentality has a periodical movement corresponding to the movement or operation of the printing press and a periodic reverse movement. in direc- 4 tion opposite to the direction of movement of the sheets. so that the said. punching instrumentality shall operate upon succeeding and adjacent sections of the sheet in the order and mannerrequired.

. Referring to the drawings, which illus- Serial No. 448,363.

trate merely by way of example, suitable means for effecting my invention Fig. 1 is a side elevation.

Fig. 2 is a view in perspective of the punching elements, on an enlarged scale.

Fig. 3 is a vertical cross-section on line 33 of Fig. 1. also on an enlarged scale.

Fig. 4 is av plan view of element 11.

Similar numerals refer to similar parts throughout the several views.

In the arrangement shown by way of example. in Fig. l. the sheet or strip of paper 7 is led from the paper roll 7. over the impression cylinder or tvmpan 8. and between said tympan 8 and the type cylinder from which it is led in a horizontal path in the direction indicated by the arrow. The sheet 7 in its horizontal travel passes he tween the upper and lower punching blocks or elements 10 and 11. and has a continuous movement during the operation of the rotarv printing press.

The lower punching block or element 11 is provided with the strips or lusts 12 having the channels 13 cooperating with the tracks 14. mounted on the sides of the stationary frame 15. so that said element 11 has a horizontal movement on said tracks 14. In order to prevent vertical movement or displacement of element 11. plates 16 are secured to the undersides of lugs 12 and proiect beneath the side margins ot track 14. Contact pieces 1'7 are provided in recesses in the upper surface of said strips 16. and set screws 18 cooperate therewith for main taining: adptstable engagement with the under margins of track 14. a

The upper punching block or element 10. is secured to the element 11 by means. for exampleof the posts or pins 19. but is capable of a relative vertical movement thereon. with respect to element 11 as shown in Fig. 2.

Other or additional means for guiding' the relative vertical movement of one punching element with respect to the other may obviously be used. c

In the present example the element 10 is provided upon its under face with a pluralit-y of suitably positioned punches 20, mo

adapted to register exactly and cooperate with corresponding holes 21 provided in the upper face of element 11.

The reciprocating movement of the punching elements is such that, during the punch ing operation, they shall move horizontally in exact unison or synchronously, with the travel of sheet 7. And after said punching operation has been completed, the blocks are returned to initial position, so that the cycle may be repeated.

In the present example, the punching de vice is adapted to punch eighteen holes in one operation, and as the printing roller is adapted to print 54 labelsduringone complete rotation, it follows that there must be three punching operations and consequently three complete forward and back horizontal movements of the punching blocks, with each rotation of the printing cylinder 9.

This actuation is secured, for example, by the following mechanism. Suitably mounted on a part of the stationary frame 15 is the cam 22, provided with a camway 23, adapted to cooperate with roller 24 secured to a lever 25, the fulcrum of which is the adjustably supported pivot 26. The upper or free end of lever 25 is adj-ustably secured in the slot 28 ofconnecting rod The other end of connecting rod 29 is pivotally connected as at 30, with the lower punch block or element 11.

The cam 22 is geared or otherwise ar' ranged in such operative relationship with the shaft of either cylinder-8 or cylinder 9, so that said cam shall make three complete rotations with each rotation of said cvlinders 8 and 9. I i

It will thus be understood that, by a proper designing of the cam-way 23, and a suitable relative adjustment of the other connecting elements, the blocks or elements 10 and 11 will be given a forward horizontal movement (to the left), which will be in exact unison, as to speed of travel, with the. travel of the sheet 7, moving from the cylinders 8 and 9, and that said elements or blocks 10 and 11 will have a quick return movement to the right) to initial position; said forward and back reciprocation occurring three times during each complete rotation of impression cylinder 8.

The extent or limits of horizontal movements of the blocks, and the speed of said movements in each direction, relatively to the peripheral speed of the cylinders 8 and 9. will be exactly controlled by theshape of the cam-way 23, and the adjustment of the connecting mechanism between said camway and said blocks or elements 10 and 11.

It will be understood that the operation must ,be such, that, in the quick return movement, allowing for the constant travel of the sheet, the punching blocks will reach initial position and start in the forward the next succeeding series of labels to be operated upon.

T he relative movement rertica-lly between blocks or elements 10 and 1].

In the position midway between the two extremes of the reciprocative movements of the blocks or elements 10 and 11. as shown in l, the blocks are relatively in position of closest engagement, that is with the punches 20 of element 10, having passed through sheet 7 and into the holes 21 of element 11. At each end of said reciprocative movement. element 10 is lifted above element 11, as shown in Fig. 3: that is with the punches 2O lifted above the top margins of holes 21, so that the sheet 7 may pass or travel freely beneath the punches and over thetop faceof element 11.

As the elements 10 and 11 travel forward, that is to-the left, in direction indicated by the arrow element 10 is given a downward vertical movement, toward element 11. By thetime the blocks reachthe middle part of their range of horizontal movement, the blocks and the sheettraveling horizontally at the-same rate of speed, the blocks are brought together, and the punches 20 pass through the sheet, and enter the holes- 21 of element 11. During the balance of the forward horizontal movement to the left, the blocks have a separating movement so that at the end of said forward movement, the punches 20 are again raised out of holes 21 and clear of the sheet 7 and are so main tained during the return movement to initial position.

This vertical relative movement between elements 10 and 11, during their horizontal movement is secured by the following mechanism: A suitable journal bearing mounted upon the table or frame 15, is provided for the shaft 31, having the eccentric 32 adjust-ably connected therewith. To eccentric S2 is connected the eccentric rod 33, the free end of which is pivotally connected, as at 34;. to the block or element 10. This rod 33 is adjustable as to its length. Eccentric shaft 31 and eccentric 32 are given such rotation relatively to the operation of the cylinders 8 and 9, that midway the forward horizontal movement of the blocks 10 andv As indicated in the drawings, the connect-.

ing rods 29 and 33 and necessary connecting mechanisms are provided on each side of the blocks in order to balance the stresses.

It will thus be clear that when the blocks move from initial position, horizontally forward, to the left, the block 10, being capable of vertical movement on the posts 19, and controlled by the eccentric rod 33, will gradually descend, causing a complete punching of the paper about midway its forward hori- Zontal travel. It will then be gradually elevated to the end of the forward horizontal movement and will be maintained elevated during the return horizontal stroke, to permit of the free passage of the sheet beneath the ends of punches 20, and over the top of element 11.

What I claim is 1. The method of punching in a continuously moving sheet, a plurality of evenly spaced holes simultaneously in exact register with devices printed on the sheet, which consists in reciprocating cooperating punching elements synchronously with the printing operation, one element moving at all times in a straight line path of travel.
